Ibn Sina: His Philosophy of Being
By R. L. Raval
Summary
This philosophical essay introduces the ontology of Ibn Sīnā (Avicenna), emphasising his distinction between essence and existence. The author outlines Ibn Sīnā’s demonstration of a Necessary Existent, from which emanate a hierarchy of intellects and celestial spheres. The article explains how Ibn Sīnā reconciles Aristotelian categories with Neoplatonic emanationism, presenting a cosmos in which contingency and necessity are clearly differentiated. It examines his theory of being as the most universal concept and explores how his metaphysical insights influenced later Islamic, Jewish and Christian thinkers. By summarising key arguments from works such as “al‑Shifāʼ” and “al‑Najāt,” the article highlights Ibn Sīnā’s lasting contribution to metaphysics.
Conclusion
The author concludes that Ibn Sīnā’s nuanced analysis of being, particularly his distinction between necessity and contingency, laid foundations for much of medieval metaphysics. By articulating a comprehensive cosmology and proof of the Necessary Existent, he provided a framework that deeply influenced subsequent philosophical traditions.
